TEN 1 TROY OZ 24k GOLD CLAD/PLATED DOUBLE BUFFALO / BISON ART BARS, THE SAME BARS THAT ARE IN PICTURE . THESE ARE BEAUTIFUL, POLISHED BARS. THIS IS FOR 10 - 1 TROY OZ 24k GOLD LAYERED BARS. I BELIEVE THE CORE IS COPPER BUT IT IS HARD TO TELL WITHOUT CUTTING DEEP PAST THE GOLD AND DESTROYING THE BAR. EACH BAR IS 1 TROY OZ. THESE BARS ARE A TRUE COLLECTORS KEEPSAKE!!!
